arnica & st. john's wort

i just got my package from mountain rose herbs (mountainroseherbs.com) of arnica (Arnica montana) and st. john's wort (Hypericum perforatum). i am infusing them both in olive oil - and then i will make a salve.

infused arnica oil is beneficial for muscle aches, injured muscles, sprains, bruises, dislocations, swelling due to fractures, trauma to soft tissue, rheumatic pain, and inflammation from insect bites. since arnica oil increases the blood supply to an inflicted area, do not appply it to an open wound because it  will cause more external bleeding

use the oil of st. john's wort for relieving pain and injuries to nerves. it can also ease the pain of sunburn. i read somewhere - that the medicinal properties actually soak into the skin and help lessen the pain from nerve injuries.
